The volatilomic fingerprint of nine different whiskeys was established using a rapid and sensitive analytical approach based on dispersive liquid–liquid microextraction (DLL?E) followed by gas chromatography mass spectrometry detection (GC-MS) with flame ionization (GC-FID). influence the extractor solvent extraction efficiency volatile compounds (VOCs) evaluated DLL?E/GC-MS. highest amounts VO...

Many real-world problems have interesting symmetries. Encoding these problems into CNF formulas generally results in hard SAT problems. Examples includes the pigeon hole problem, which, although very simple, is nonpolynomial for any resolution-based method when encoded into SAT [6], and the n queen problem. In order to speed up search algorithms for these problems, intrinsic symmetries should b...

Insects are easily distinguishable by the absence of legs on the adult abdomen. Studies performed on the Dipteran, Drosophila melanogaster, indicate that this is because of the repressive effects of the homeotic genes Ultrabithorax (Ubx) and abdominal-A (abd-A) on the limb promoting gene Distal-less (Dll) during embryonic development. However, in many species appendage-like structures are prese...

Specialized dendritic cells (DCs) within the thymus are crucial for the deletion of autoreactive T cells. The question of whether these cells arise from intrathymic precursors with T-cell potential has been hotly debated, and the regulatory pathways and signals that direct their development remain unclear. Here, we compared the gene expression profiles of thymic DC subsets with those of four ea...

A combined PLL/DLL algorithm is developed for tracking GNSS carrier phase and code phase using the output from a large number of correlators. This approach has advantages for limb-scanning applications, in which useful meteorological information, available only at the initial rising time of a GPS satellite, is desired. The technique uses the bank of correlators to span wide ranges of uncertaint...

Dual threshold voltages domino design methodology utilizes low threshold voltages for all transistors that can switch during the evaluate mode and utilizes high threshold voltages for all transistors that can switch during the pre charge modes. We employed standby switch can strongly turn off all of the high threshold voltage transistors which enhances the effectiveness of a dual threshold volt...

A class of space-time block codes is proposed and optimized for the quasi-static multi-input multi-output (MIMO) Rayleigh fading channel. These codes use single-input single-output (SISO) component codes based on algebraic number theory in a diagonally layered architecture, and are hence referred to as diagonally layered lattice (DLL) codes. A salient feature of the DLL codes is that they have ...

Background: Acute Myeloid Leukemias (AMLs) are neoplastic proliferations arising in hematopoietic precursor cells the bone marrow resulting overgrowth of myeloblasts and other myeloid lineage. Notch-1 receptor is a transmembrane protein type I. Interactions between its ligands Jagged-1 Dll-1 result proteolytic cleavages inside receptor, followed by release nuclear translocation intracellular do...

Resolution is the rule of inference at the basis of most procedures for automated reasoning. In these procedures, the input formula is first translated into an equisatisfiable formula in conjunctive normal form (CNF) and then represented as a set of clauses. Deduction starts by inferring new clauses by resolution, and goes on till the empty clause is generated or satisfiability of the set of cl...
